Vantaggi
Not everyone will be your person, but the ones who are, you'll keep them for life. The intensity of the work forges real bonds. When you go through the grind together, those friendships/mentorship stick long after you've moved on. Same goes for upper management.
Svantaggi
During busy season (approx Jan to April), 40 hours is a floor, not a ceiling, and that's pretty standard for firms of this type. On the consulting side, you're constantly juggling multiple clients with overlapping deadlines, so if time management isn't your strong suit, you'll feel it fast. Compensation is solidly middle-of-the-road; don't expect it to wow you.
